Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to the difficulty in consistently producing superior genetic combinations.

Innovation Solution

The development of the soybean variety D5886524, which includes methods for crossing and breeding to introduce specific traits like herbicide resistance, disease resistance, and improved nutritional quality through genetic transformation and backcrossing, allowing for the creation of hybrid seeds and plants with consistent desirable characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used, then soybean varieties can be developed with desirable traits, but the process is time-consuming and unpredictable

Engineering Contradiction:
Improvepredictability of trait combinationVSAvoidbreeding program duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (disease resistance, yield potential, nutritional quality) before crossing. The breeding program establishes clear selection criteria and pre-characterizes parental germplasm to ensure predictable trait inheritance in progeny, reducing the time required for random selection and evaluation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through systematic evaluation of breeding progeny for desired traits. Performance data from field trials and laboratory analyses are fed back into the breeding program to guide subsequent crossing decisions and selection processes, improving predictability and efficiency of developing superior varieties.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the breeding complexity increases

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct phases: parental line selection, controlled crossing, progeny evaluation, and variety registration. Each phase focuses on specific traits (e.g., disease resistance in one phase, yield in another), making the complex task of combining multiple traits more manageable and systematic.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges multiple parental lines with different desirable traits into a single superior variety through controlled hybridization. By systematically combining traits from different parental germplasm sources and evaluating the progeny, the program achieves versatile varieties that exhibit multiple improved characteristics simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If selection pressure is increased to improve yield and resistance traits, then variety quality is enhanced, but genetic diversity may be reduced

Engineering Contradiction:
Improvetrait uniformityVSAvoidgenetic diversity
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by applying different selection pressures to different traits in different breeding phases. Specific traits like disease resistance are strongly selected for in early generations, while genetic diversity is maintained through inclusion of multiple parental lines with diverse backgrounds. This allows high uniformity for key traits while preserving overall genetic versatility.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes selection parameters throughout the breeding program - starting with broad trait selection from diverse parents, then progressively increasing selection intensity for specific high-value traits like yield and resistance. This dynamic adjustment of selection parameters allows maintenance of genetic diversity early in the program while achieving trait uniformity in the final variety.

Inventive Principle:
Principle #35Parameter changes
